NTRODUCTION
The Aqua-Hot Heating System is a Low Emissions Hy-
dronic Heating System (heating with hot water) that sig-
nificantly improves your level of comfort, is good for the
environment and adds thousands of dollars in value to
your RV.
The Aqua-Hot Heating System is actually four sys-
tems in one:
•
Interior heating system providing quiet, comfortable
interior heat with independent temperature zones that
provide cabin-wide even temperatures.
•
Bay heating system keeps pipes and tanks from
freezing in the bay storage area.
•
Tank-less hot water system provides a steady flow of
continuous hot water.
•
Engine preheating system reduces engine wear
caused by cold starting by preheating the engine
from 30°f to 90°f in one hour.
Your Aqua-Hot System is powered by TribridHot
™
technology, using one or a combination of sources:
•
The Vehicle’s Engine: When driving or idling, the en-
gines surplus heat is transferred to the Aqua-Hot pro-
viding interior heat and limited hot water without
burning any other fuel.
•
The 120v AC Electric Element: When plugged into
shore power, the electric element lets you use the
power you are already paying for to provide interior
heat and meet your light duty hot water needs.
•
The Diesel Burner: The Aqua-Hot’s most powerful
heat source provides all of your heating and hot wa-
ter needs in really cold temperatures or when dry
camping.
You can even combine power sources. TribridHot
